TEIN PRH01-31S70 Pillow Ball Upper Mount - Front

The TEIN PRH01-31S70 is a precision-engineered pillow ball upper mount designed to replace the factory rubber upper mount with a high-performance spherical bearing alternative. This front upper mount features a pillow ball (spherical bearing) design that eliminates the deflection and compliance found in OEM rubber bushings, delivering sharper steering response and improved suspension feedback.

Key Features:

• Precision pillow ball (spherical bearing) design eliminates rubber bushing deflection
• Model-specific design maintains optimal spring and shock positioning
• Ultra duralumin A2017S-T4 aircraft-grade aluminum construction with anodized finish
• High-grade NMB pillow ball bearings for superior durability
• Minimizes height change and maintains stroke center
• Reduces alignment changes under load for improved tire grip
• High-tension S45C steel serration bolts for secure mounting
• Spring inner diameter: 70mm

This pillow ball upper mount is designed to work with TEIN coilover systems and compatible aftermarket suspension setups. The replacement of rubber bushings with precision bearings allows for more direct suspension response, better alignment stability during cornering, and enhanced steering feel. The aircraft-grade aluminum construction ensures maximum strength while keeping weight to a minimum.
